The Siemens SENTRON 3VA1096-3ED32-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current at 40 °C, with a TM210 thermal-magnetic release. That 16 A holds flat through 50 °C — only above 55 °C does it begin to derate, dropping to 15.36 A at 55 °C and 14.4 A at 70 °C. For a panel that runs warm, the headroom is there; you don't lose capacity until the ambient pushes past 50 °C. Breaking capacity is the real selector here: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. The 690 V rating is lower but still covers most industrial line-to-line faults.
Integration and auxiliary options
The integrated auxiliary trip order code is 3VA9688-0BL30 — that's the specific accessory module that mates to this frame. No undervoltage release, no communication module, no phase failure detection; this is a straightforward line-protection MCCB with a voltage-trigger function for remote tripping. The latching endurance is rated at 15 000 cycles, which is typical for a distribution-grade MCCB not intended for frequent switching duty.
